VMM 2 SRS Hybrid – Status A few modifications under way: • Access to analog monitor outputs for calibration and debug • Layout changes to improve power distribution and decoupling • Separate power option • Also, digital DCARD is being modified to provide the needed power to the VMM Hybrid (1. 5 A/hybrid) 7

FECv 6 • Upgrade of the FEC board with Virtex-6 FPGA • Production batch ordered by CERN Store at Samway Electronics, Bucharest • First samples arrived at IFIN-HH for initial testing • So far no problems detected • Full verification procedure is now being defined 8

FECv 6 - Firmware • Beta firmware port (raw APV data over Ethernet) tested successfully by Eraldo with APV Feature integration pending: • DTCC link to SRU • A lot of input from Andre (Munich) and Raul (Valencia) • Ethernet and DTTC versions may be merged into a single FW variant • APV Zero suppression • VMM 2 logic 9

High Density Optical Mezzanine for ATCA-SRS 25 LVDS • Build under specification for ATLAS NSW Trigger Processor • 2 x Virtex-7 FPGA (356 K – 477 K logic cells) • 72 RX + 72 RX Optical (36/36 each FPGA) 64 LVDS • Avago Micropods • > 900 Gbps integrated front-end bandwidth • Possibility to have light/low-cost version 36 TX 36 RX (1 x FPGA / 36 optical connections) • Prototype board is in our hands • First tests pending 10
